Laboratory and Diagnostic Testing during the First Prenatal Visit
Done to screen for abnormal results; intervention can be implemented as soon as possible or at follow-up visits, as indicated
Complete blood count (CBC)
A series of blood tests that provide information on the hematologic system as well as other body systems; advantages include that it is inexpensive, easy to perform, and results are quickly available
Blood group and Rh typing
To determine the client's blood group and Rh status to identify a fetus at risk for developing erythroblastosis fetalis or hyperbilirubinemia in the neonatal period
TORCH
A group of infection caused by viruses and protozoa that cause serious fetal problems when contracted by the mother during pregnancy
Toxoplasmosis
Infection with the protozoan parasite toxoplasma gondii
Toxoplasmosis transmission
Development of this infection in the mother is associated with consumption of infested undercooked meat and poor hand-washing after handling cat litter
Toxoplasmosis diagnostics
Serologic testing; the indirect fluorescent antibody test is the most commonly used
Toxoplasmosis maternal effects
Flu-like symptoms in acute phase
Toxoplasmosis fetal/neonatal effects
Miscarriage is likely in early pregnancy; in neonates central nervous system lesion can result in hydrocephaly, microcephaly, chronic retinitis, and seizures
Other infections, usually Hepatitis Virus
Infection with the hepatitis A or B virus; hepatitis B is the most common in the fetus
Hepatitis transmission
Hepatitis B can be transmitted to the fetus via the placenta, but transmission usually occurs when the infant is exposed to blood and genital secretions during labor in delivery
Hepatitis diagnostics
Hepatitis B is detected through the hepatitis B surface antigen (HbsAg)
Hepatitis maternal effects
Fever, malaise, nausea, and abdominal comfort; may be associated with liver failure
Hepatitis fetal/neonatal effects
Preterm birth, hepatitis infection, and intrauterine fetal death
Rubella
Infection with rubella virus, sometimes called German measles or 3-day measles
Rubella transmission
Spread through droplet
Rubella diagnostics
An IgG antibody are measured to determines client's rubella immunity status
Rubella maternal effects
Fever, rash, and mild lymphedema
Rubella fetal/neonatal effects
Miscarriage, congenital anomalies, and death
Cytomegalovirus (CVM)
Exposure to cytomegalovirus
CVM transmission
CVM can be transmitted through respiratory droplet, semen, cervical and vaginal secretions, breast milk, placental tissue, urine, feces, and banked blood
CVM diagnostics
Viral culture is the most definitive diagnostic tool; CVM antibodies indicate a recent infection
CVM maternal effects
Asymptomatic illness, cervical discharge, and mononucleosis-like
Syndrome
A group of symptoms that occur together and characterize a particular abnormal condition
Herpes Simplex Virus (HSV)
A virus that causes a contagious infection
Sexually Transmitted Infections (STIs)
Also called venereal diseases, caused by bacteria, viruses, protozoa, or ectoparasites
Human papillomavirus (HPV)
Sometimes called genital or venereal warts, caused by spread of the HPV through sexual contact
Human Immunodeficiency Virus (HIV)
A virus that causes a chronic and potentially life-threatening condition
Group B Streptococcus (GBS)
A type of bacteria that can cause serious infections in newborns
Syphilis
A sexually transmitted infection caused by the bacterium Treponema pallidum
Gonorrhea
Caused by Neisseria gonorrhoeae, an aerobic, gram-negative diplococci bacteria, transmitted by all types of sexual activity; neonates can acquire the infection by exposure to the bacteria in the birth canal
Chlamydia
The Chlamydia trachomatis bacteria is spread through sexual contact
The pH may be decreased with poor glucose metabolism and ketone acids in the urine
Specific gravity may be increased with dehydration caused by excessive vomiting as seen in hyperemesis gravidarum
Color should be pale yellow to amber depending on foods ingested and concentration
Glucose reabsorption is impaired in pregnancy resulting in spilling of glucose in urine at a blood glucose level of 160mg/dL
Protein may normally be found in the urine during pregnancy at a level of trace to +1 using the dipstick method; increased protein may indicate pregnancy induced hypertension (gestational hypertension)
WBCs or nitrates can indicate a possible UTI which can place the clients at risk for preterm labor
Casts, which are formed from clumps of materials or cells in the renal distal and collecting tubules, form when the urine is acidic and concentrated; they can be associated with proteinuria and stasis in the renal tubules
